[0046] To reduce the difficulty of assembly and welding, increase the convenience of construction, and improve welding quality, this embodiment provides a method for manufacturing a ship's bow.

[0047] like Figure 1 As shown, the manufacturing method of the ship's bow includes the following steps:

[0048] S1. Segmented fabrication of keel web 1, keel panel 2, horizontal baffle 3, transverse rib 4, bow outer plate 5, and hull outer plate 6.

[0049] S2. Manufacture auxiliary lining plate 7. The shape of auxiliary lining plate 7 is consistent with the shape of keel panel 2, but the width of auxiliary lining plate 7 is smaller than the width of keel panel 2.

[0050] S3. Weld the auxiliary liner 7 to one end of the keel web 1 along the first direction;

[0051] S4. Horizontal baffles 3 are provided on both sides of the keel web plate 1 along the second direction. First, the horizontal baffles 3 are welded and fixed to the auxiliary liner plate 7, and then the horizontal baffles 3 are welded to the keel web plate 1.

[0052] S5. The keel web plate 1 is provided with transverse ribs 4 on both sides along the second direction. First, the transverse ribs 4 are welded and fixed to the auxiliary liner plate 7, and then the transverse ribs 4 are welded to the keel web plate 1.

[0053] S6. Place the outer bow plate 5 at the other end of the keel web plate 1 along the first direction, and weld and fix the outer bow plate 5 to the keel web plate 1, the horizontal baffle 3 and the transverse rib plate 4.

[0054] S7. Both sides of the bow outer plate 5 along the second direction are provided with hull outer plates 6. The hull outer plates 6 are mated to the corresponding bow outer plates 5 and welded to the bow outer plates 5, the horizontal baffles 3 and the transverse ribs 4 respectively.

[0055] S8. First, weld the keel panel 2 onto the auxiliary liner 7, and finally weld the horizontal baffle 3 and transverse rib 4 that are in contact with the keel panel 2.

[0056] By first welding auxiliary lining plates 7 onto the keel web 1, and then using the auxiliary lining plates 7 to sequentially weld the horizontal baffle 3, transverse ribs 4, bow outer plate 5, and hull outer plate 6, and finally welding the keel panel 2, the auxiliary lining plates 7, being narrower than the keel panel 2, allow for sufficient operating space for effective welding of the hull outer plate 6 to the horizontal baffle 3, transverse ribs 4, and bow outer plate 5. This reduces the difficulty of assembling and welding the bow, greatly increases the convenience of construction, and improves the welding quality.

[0057] Optionally, such as Figures 2 to 5 As shown, in step S4, multiple horizontal baffles 3 are welded to both sides of the keel web 1 along the second direction and spaced apart along the third direction. By welding multiple horizontal baffles 3 spaced apart along the third direction, the structural strength of the manufactured ship's bow is improved, ensuring the quality of the ship's bow. In this embodiment, the horizontal baffles 3 are welded to the keel web 1 using fillet welds, and in this embodiment, six spaced horizontal baffles 3 are provided on one side of the keel web 1, controlling costs while meeting structural requirements.

[0058] Optionally, as shown in Figure 2 , Figure 3 , a plurality of transverse ribs 4 are arranged along the first direction on both sides of the keel web 1 along the second direction in step S5. By welding a plurality of transverse ribs 4 arranged along the second direction, the structural strength of the ship bow manufactured is improved, and the quality of the ship bow is ensured. In this embodiment, the transverse ribs 4 are welded and fixed to the keel web 1 by fillet welding, and in this embodiment, two transverse ribs 4 are arranged on one side of the keel web 1. The cost is controlled on the basis of meeting the structure.

[0059] Optionally, the butt joint surface of the hull outer plate 6 and the bow outer plate 5 is flush with the keel panel 2 in step S7. By making the butt joint surface flush with the keel panel 2, the butt joint surface is supported after the keel panel 2 is subsequently welded, thereby enhancing the structural strength.

[0060] Optionally, as shown in Figure 4 , the butt joint surface of the hull outer plate 6 and the bow outer plate 5 passes over the keel panel 2 along the first direction in step S7. By making the butt joint surface pass over the keel panel 2, interference of the butt joint surface with subsequent welding of the keel panel 2 is avoided.

[0061] Optionally, as shown in Figure 2 , the first auxiliary plate 8 is welded on the keel panel 2 in step S8, and the horizontal baffle 3 in contact with the keel panel 2 is welded to the keel panel 2 through the first auxiliary plate 8. By providing the first auxiliary plate 8, not only is the horizontal baffle 3 conveniently welded to the keel panel 2, but also the contact area between the horizontal baffle 3 and the keel panel 2 is indirectly enlarged through the first auxiliary plate 8, thereby improving the structural strength.

[0062] Optionally, as shown in Figure 2 , the second auxiliary plate 9 is also welded on the keel panel 2 in step S8, and the transverse rib 4 in contact with the keel panel 2 is welded to the keel panel 2 through the second auxiliary plate 9. By providing the second auxiliary plate 9, not only is the transverse rib 4 conveniently welded to the keel panel 2, but also the contact area between the transverse rib 4 and the keel panel 2 is indirectly enlarged through the second auxiliary plate 9, thereby improving the structural strength.

[0063] Optionally, as shown in Figure 6 , the keel panel 2 and the auxiliary lining 7 are welded by plug welding. By using plug welding to weld the keel panel 2 and the auxiliary lining 7, no ruler is needed before welding, which is efficient and aesthetically pleasing. In this embodiment, the keel panel 2 is provided with a plurality of plug welding holes 21 for plug welding.

[0064] Optionally, the auxiliary lining plate 7 is a steel lining plate. By using a steel lining plate as the auxiliary lining plate 7, welding is facilitated, and the material is easy to obtain and process, thereby reducing the cost and manufacturing difficulty.

[0065] In the embodiment, a ship bow is also provided, which is manufactured by the above-mentioned manufacturing method of the ship bow. Since the manufacturing method of the ship bow reduces the construction difficulty and improves the welding quality, the working time is greatly reduced, and the assembly efficiency and product quality are improved.

[0066] Obviously, the above-mentioned embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application.
